Declaration

static func rootMeanSquare<U>(_ vector: U) -> Float where U : AccelerateBuffer, U.Element == Float

Parameters

  • vector:

    The source vector.

Discussion

This function calculates and returns the root mean square of a supplied vector.

The following is an example of using rootMeanSquare(_:):

    let a: [Float] =  [-8, -4, -2, 0, 2, 4, 8]

    let rms = vDSP.rootMeanSquare(a)
    
    print(rms) // Prints "4.89".
